Setting the Switch’s IP Address (IP Version 6)
– 669 –
IPv6 Neighbor Discovery Protocol supersedes IPv4 Address Resolution Protocol
in IPv6 networks. IPv6 nodes on the same network segment use Neighbor
Discovery to discover each other's presence, to determine each other's link-
layer addresses, to find routers and to maintain reachability information about
the paths to active neighbors. The key parameters used to facilitate this process
are the number of attempts made to verify whether or not a duplicate address
exists on the same network segment, and the interval between neighbor
solicitations used to verify reachability information.
Parameters
These parameters are displayed:
VLAN Mode
VLAN ID of a configured VLAN which is to be used for management access, or
as a standard interface for a subnet. By default, all ports on the switch are
members of VLAN 1. However, the management station can be attached to a
port belonging to any VLAN, as long as that VLAN has been assigned an IP
address. (Range: 1-4094)
Enable IPv6 Explicitly – Enables IPv6 on an interface and assigns it a link-local
address. Note that when an explicit address is assigned to an interface, IPv6 is
automatically enabled, and cannot be disabled until all assigned addresses
have been removed. (Default: Disabled)
Disabling this parameter does not disable IPv6 for an interface that has been
explicitly configured with an IPv6 address.
MTU – Sets the size of the maximum transmission unit (MTU) for IPv6 packets
sent on an interface. (Range: 1280-65535 bytes; Default: 1500 bytes)
The maximum value set in this field cannot exceed the MTU of the physical
interface, which is currently fixed at 1500 bytes.
If a non-default value is configured, an MTU option is included in the router
advertisements sent from this device. This option is provided to ensure that
all nodes on a link use the same MTU value in cases where the link MTU is
not otherwise well known.
IPv6 routers do not fragment IPv6 packets forwarded from other routers.
However, traffic originating from an end-station connected to an IPv6
router may be fragmented.
All devices on the same physical medium must use the same MTU in order
to operate correctly.
IPv6 must be enabled on an interface before the MTU can be set. If an IPv6
address has not been assigned to the switch, “N/A” is displayed in the MTU
field.
ND DAD Attempts – The number of consecutive neighbor solicitation
messages sent on an interface during duplicate address detection.
(Range: 0-600, Default: 1)
